White-rimmed shingle lichen

Fuscopannaria leucosticta, commonly known as the rimmed shingle lichen, is a species of lichen in the family Pannariaceae. It has a squamulose (scaley) thallus that lacks soredia and isidia (vegetative propagules), but has abundant apothecia (spore-bearing structures) with distinct white rims. Although its main centres of distribution are eastern North America and southeast Asia, where it grows in damp forests, it has been reported from various other high-altitude, humid locations.
